Ran a new set of ds2500s with HC disks, braided lines and ATE superblue and they didn't fade all day at Cadwell. Was given plenty of hammer as 2 of us share the car and there's some real hard braking points round that track.
Same set up i had when i did Cadwell,had good strong predictable brakes all day. Great track aswel.
Nick hit nail on head, people are always going to suggest the products they sell.
Brakes are subjective like tyres, some people love a certain tyre and another person thinks they're average.
You pay your money you make your choice.
Stick to the bigger well known brands and you won't go far wrong.
Also i have never had any feedback of Brembo Max discs cracking, and i have sold a few sets to various cars that get used properly on track. Some of the cheaper drilled discs that are floating about can crack though
